appear in industrial environments. In environments with unknown disturbance level it is recommended to use the

following preventive measures:

� without proper line filters do not provide the power supply to the controller from the same lines which supply

large equipment;

� use screened power supply, sensor and signal cables; the screen earthing shall be one-point type, located as

close to the device as possible;

� avoid placing the measuring (signal) leads in direct vicinity of and parallel to power supply cables or lines;

� it is recommended to twist the signal leads in pairs;

� use identical leads for resistance sensors in 3-lead connection;

� avoid proximity of remotely controlled devices, electromagnetic meters, large electrical loads, loads with phase

or group power control, and other devices generating large pulse disturbance;

NOTE:

To install the cabling in the AR632, follow the instructions given below:

− remove 4 bolts in the front panel and remove the panel;

− fasten the controller to the base using 4 screws and fastening holes;

− remove one bolt on the display board and carefully pull out the board from its seats;

8

− now you have access to terminals to connect the signal, power supply, and relay outputs leads;

− insert the leads to the controller through cable glands;

− after connecting, reassemble the controller in reverse order;

− to get the IP65 rating, precisely tighten the glands’ nuts and the enclosure cover;

− to prevent mechanical and electrostatic damage, exercise particular caution when handling the display board.

a.4) AR662 – terminals description Table 7

NOTE:

To connect to the computer via the PRG socket, use only the AR955 programming device (with optional adapter

for AR602). Connection using the simple USB cable can damage the controller.

b) connecting 2- and 3-lead transmitter (Iout - current, Uout – output voltage)

8. IMPORTANT TIPS – using the suppression systems

! If an inductive load (e.g. contactor coil, transformer) is connected to the relay contacts, overvoltage and arc

appear often during opening as a result of discharge of energy accumulated in the inductance. Particularly

harmful effects of such overvoltage include reduced life of contactors and relays, destruction of semiconductors

(diodes, thyristors, triacs), damage or disturbance of control and measurement systems,

emission of electromagnetic fields causing interference with local devices. To avoid such

effects, the overvoltage must be reduced to a safe level. The easiest method is connecting a

suitable suppression module directly to the inductive load terminals. Generally, a suitable

type of suppression system should be selected for each inductive load. Modern contactors usually have factory-

installed suitable suppression systems. If they do not, a contactor with a built-in suppression system should be

bought. Temporarily, you can shunt the load using the RC system, e.g. R=47Ω/1W and C=22nF/630V. Connect the

suppression system to the inductive load terminals. This will limit burning of the relays contacts in the controller

and reduce the probability that they will get stuck.

Description the front 7-segment LED display

elevation for

example AR652 programming buttons

LED indicators

a) functions of buttons in the measurement display mode

Button Description [and designation in the manual]

[UP] or [DOWN]: change set value for input 1 (parameter 9: or 26: when

output 1 is in manual mode (see sections 10 and 12.8)

[SET] :

- go to the quick access menu (see section 11)

[UP] and [DOWN] (simultaneously): go to the parameter configuration menu (if pressed

for longer than 1 s). If the parameter 33: PPro = on (password protection on), enter the

access password, section 10)

[F] (unavailable in AR602): start the function programmed by parameter 34: Func (if

pressed for longer than 1 s, sections 9.1 and 10)

b) functions of buttons in the parameter configuration menu and quick access menu (sections 10 and 11)

Button Description [and designation in the manual]

[SET] :

- edit current parameter (the value in the bottom display is flashing)

- confirm and save the edited parameter

[UP] or [DOWN]:

- go to the next parameter

- change the value of current parameter

[UP] and [DOWN] (simultaneously):

- cancel the modifications of edited value (flashing stops)

- return to the measurement display mode (if held for > 0.5s)

c) functions of signal LED indicators

LED indicators [designation] Description

[1] [2] [3] inputs P1/SSR1, P2/SSR2, P3/SSR3 are on

9.1. FUNCTION BUTTON AND BINARY INPUT

Function button [F] (unavailable in AR602) and binary input BIN perform the same function programmable by

parameter 34: Func (section 10). The binary input cooperates with the bistable signal, i.e. the received signal

(voltage or switch) must be of durable character (on/off type). In addition, the [F] is inactive when the BIN is active

(short-circuit or voltage <0.8V). Starting and stopping of the function is signalled by relevant message on the

bottom display (described in Table 9.1).

10. SETTING THE CONFIGURATION PARAMETERS

All configuration parameters are stored in a non-volatile internal memory. When the controller is switched on for

the first time, an error message may appear indicating that there is no sensor or that the sensor is different than

programmed. Connect the right sensor or perform the configuration programming.

There are two methods of parameter configuration:

1. Using the keypad on the front panel:

− from the measurement display mode go to the configuration menu (simultaneously press [UP] and

[DOWN] buttons for longer than 1 s). If the parameter 33: PPro = on (password protection on), the display

will show the message CodE and then 0000 with the first digit flashing. Use the [UP] or [DOWN] buttons

to enter the access password (default parameter 32: PASS = 1111 ). Use the [SET] button to go to

successive positions and to approve the code;

− after entering the configuration menu (with the ConF message) the main display shows the mnemonic

name of the parameter (inP <-> FiLt <-> dot <->, etc.), and the bottom one its value;

− use the [UP] button to go to the next parameter, and the [DOWN] button to return to the previous

parameter (the list of all parameters is given in table 10);

− to change the value of selected parameter, briefly press [SET] (flashing in the edit mode);

− change the value of parameter using [UP] or [DOWN] buttons;

− confirm new value by pressing [SET] or cancel: [UP] and [DOWN] (press simultaneously briefly) and the

display will again show the parameter name;

− to exit the configuration menu: press [UP] and [DOWN] simultaneously for a longer time. The controller will

exit the configuration menu automatically after about 2 min. of inactivity.

2. Via the RS485 port or PRG (AR955 programming device) and the ARSOFT-WZ1 application (section 14):

- connect the controller to the computer, start and configure the ARSOFT-WZ1 application

- when the connection is made, the program window will show the current measured value

- setting and viewing of parameters is possible in the parameter configuration window

- press the Accept Changes button to approve new values

- current configuration can be saved in a file or set using the values read from the file

- file with ready configuration can also be created using the ARSOFT-WZ4 application (section 14)

11

NOTE: !

- before disconnecting the controller from the computer press the Disconnect Device button (ARSOFT-WZ1)

- if the program does not respond:

- in Program Options check the port configuration and the MODBUS device address

- make sure that the serial port drivers in the computer have been correctly installed for the

RS485 converter or the AR955 programming device

- disconnect the RS485 converter or the AR955 programming device for a few seconds and then

reconnect

- restart your computer

If the indications are different that actual input signal value, you can tune the zero and sensitivity to a given

sensor: parameters 38: cALo (zero) and 39: cALG (sensitivity).

To restore factory settings: on powering up press [UP] and [DOWN] until the password menu appears (CodE), and

then enter the 0112 code. Alternatively, use the file with default configuration in the ARSOFT-WZ1 application.

NOTE: !

Do not configure the device from the keypad and via the serial interface (RS485 or AR955) at the same time.

configuration parameters and functions without entering the password. This opportunity is called quick access

and is available after pressing the [SET] button. The selection and editing of the parameter is analogous to the

description in section 10.

12. OUTPUTS CONFIGURATION

Programmable architecture of the controller allows it to be used in many fields and applications. Before using the

device, its parameters need to be customized (section 10). The detailed description of outputs configuration is

given in sections 12.1 ÷ 12.8. The default factory configuration is as follows: outputs 1 and 2 are in the ON-OFF

mode with hysteresis, output 3 and analogue outputs are off (Table 10, Default settings column).

12.1. CHANGING THE OUTPUTS SET VALUES

In the measurement mode the top display shows the measured value and the bottom one the output 1 set value

(parameter 9: SEt1 or 26: HSEt when the controller is in manual mode). The easiest way to change the set value is

to use the [UP] or [DOWN] buttons. Quick access menu (section 11) can be used for other outputs. As an

alternative, the modification of each set value is available in the parameter configuration mode, using methods

described in section 10.

15

12.2. TYPES OF OUTPUT CHARACTERISTICS

Type of operation of each output is programmed using the parameters 8: out1, 12: out2, and 15: out3,

section 10, Table 10.

a) basic outputs characteristics curves

b) additional outputs characteristics curves (only for outputs 2 and 3)

NOTE: * H3 is constant and equals 0.2°C (2 units), not subject to configuration

16

12.3. ANALOGUE OUTPUT

The output signal standard is determined by parameter 17: AtYP (section 10, Table 10). The analogue output can

be used in one of the following modes: measurement retransmission (parameter 18: outA = rEtr), manual (18:

outA = hAnd) and as an automatic control output (18: outA = cont).

In the measurement retransmission mode, the output signal is proportional to the signal measured in the range

set by parameters 19: A-Lo and 20: A-Hi (e.g. 0mA for the measured value 0°C when A-Lo = 0°C, 20mA for 100°C

when = 100°C, and correspondingly 10mA for the half range, i.e. 50°C ). In other words, in the retransmission

mode the output converts the input signal to the output signal (in the A-Lo ÷ A-Hi range). Manual mode (section

12.8) allows a smooth conversion of the input signal into the output signal in the 0 ÷ 100% range with 1%

increment and initial value equal to the last value in automatic mode (measurement retransmission or control).

In the automatic control mode, the parameters and functions are identical as for output 1 (applicable are 7: Fto1 ,

8: ovt1 , 9: SEt1 , 10: H1 , algorithm and PID tuning parameters and the process control).

In the control mode, the analogue signal variation range is continuous only for the PID algorithm (within the

proportionality range, section 12.4), in case of the ON-OFF mode with hysteresis the output has the extreme

values (low or high value, e.g. 0mA or 20mA), with no intermediate values.

12.4. PID CONTROL

The PID algorithm gives smaller control errors (e.g. temperature) than the

ON-OFF method with hysteresis. However, this algorithm requires the

selection of typical parameters for a given controlled facility (e.g. a

furnace). To simplify the use, the controller is equipped with advanced

functions of selecting the PID parameters which are described in section

12.5. In addition, it is always possible to correct the settings manually

(section 12.6).

The controller operates in the PID mode when the proportionality range

(parameter 22: Pb) is non-zero. Relation between the proportionality

range Pb and the set value SEt1 is shown in figures 12.4 a) and b). The

impact of the integration and differentiation is defined by the

parameters 23: and 24: . The parameter 25: determines the

pulsing period for output 1 (P1/SSR1). When the PID algorithm is effected

by the 0/4÷20mA or 0/2÷10V analogue output, the parameter is

irrelevant. In that case, the output signal can have any intermediate value

from the entire output variability range.

Regardless of the output type, the output status is always adjusted

every 1s. The principle of operation of the P type (proportional) control for output

1 is shown in figures d), e), for analogue output in figure c).

Fig. 12.4. PID control - principle of operation:

a) Relation between the proportionality range Pb and the set value

SEt1 for heating (ovt1 = inv)

b) Relation between the proportionality range Pb and the set value

SEt1 for cooling (ovt1 = dir)

c) status of analogue output 0/4÷20 mA or 0/2÷10V

d) filling ratio for output 1 (P1/SSR1)

e) status of output 1 for measured value within the proportionality range

17

12.5. AUTOMATIC SELECTION OF PID PARAMETERS

The first step to use the function of PID parameters selection is to choose the type of tuning (parameter 21: tunE,

section 10). The tuning will start automatically with start of control (after powering up, and also by pressing the

button [F], or by binary input BIN when parameter 34: Func = StSP, section 9.1). in addition, the tuning can be

stopped (oFF), and then restarted (on) at any time by using the function t-St available in the quick access menu

(section 11). When the tuning is in progress (i.e. when the display alternately shows the set value and the tvnE

message) the set value should not be changed (9: Set1 or 16: SEt3 when 34: Func = SEt3).

Value of parameter 21: tvnE determines the method of selecting the PID parameters:

a) 21: tunE = Auto - automatic selection – the controller continuously checks if there are conditions to start the

tuning and tests the facility to find a suitable method. The algorithm incessantly enforces the PID mode

operation. The necessary condition to initiate the PID parameters selection is the measured value being out of

the insensitiveness zone which is defined as the sum of parameter 22: Pb and 10: H1 in relation to set value 9:

Set1, as in figure 12.5.

Fig.12.5. Insensitiveness zone for

heating (8: ovt1 = inv) and

cooling (8: ovt1 = dir)

To avoid an unnecessary start of tuning, which may delay the process, it is recommended to set the H1 relatively

high, at least at 10÷30% of the process variability range (e.g. measured temperature variability range). The

facility testing with temporary output off and the tvnE message takes place also in the insensitiveness zone if

rapid changes of measured or set value are detected.

The method of parameters selection depends on the initial conditions. The fast step method will be used in case

of stabilized controlled value, otherwise the slower oscillation method will be applied.

The automatic selection ensures optimum PID parameters for current conditions in the facility, without the

user’s intervention. It is recommended for variable value control (disturbance of set conditions during operation

by modification of e.g. the set value or the furnace batch).

b) 21: tunE = StEP – selection of parameters in the step stage (response to step function). While determining the

characteristics of the object, the algorithm does not cause an additional delay in reaching the set value. This

method is dedicated to facilities with stabilized initial controlled value (e.g. temperature in a cold furnace). In

order not to disturb the stabilized initial conditions, before starting the autotuning, turn off the actuator’s (e.g.

the heater) power supply using an external switch, or use the control start/stop function [F] button or BIN

input). Turn on the power supply again immediately after the autotuning starts, during the output activation

delay phase. If the power supply is turned on later, the facility analysis will be incorrect and consequently the

PID parameters will not be selected correctly.

c) 21: tunE = oSct – selection of parameters using the oscillation method. The algorithm involves the

measurement of the oscillation amplitude and period at a slightly lower level for heating or a slightly higher

level for cooling than the set value in order to eliminate the danger that the target value will be exceeded

during the facility test stage. While determining the characteristics of the object, the algorithm causes an

additional delay in reaching the set value. This method is dedicated to facilities with unstable initial controlled

value (e.g. temperature in a hot furnace).

The algorithms from b and c comprise the following stages:

- output activation delay (about 15s) – time to power up the actuator (heating/cooling power, fan, etc.);

- determination of the facility characteristic curve;

- determination and saving in the controller’s non-volatile memory of parameters: 22: Pb , 23: ti , 24: td

and 25: tc

- activation of control with new PID settings.

18

The program can discontinue the autotuning b or c (with the Errt message) if the conditions for correct

algorithm operation are not met:

- initial value is higher than the set value for heating or lower for cooling;

- maximum autotuning duration (4 hours) has been exceeded;

- process value changes too quickly or too slowly.

It is recommended to perform the autotuning b or c after a significant change of the SEt1 threshold or the

controlled facility parameters (e.g. heating/cooling power, charge, initial temperature, etc.).

12.6. ADJUSTMENT OF PID PARAMETERS

The autotuning function correctly selects the PID control parameters for most processes, but sometimes the

parameters need adjustment. Due to a strong interdependence of these parameters, adjust only one of them and

observe the impact on the process:

a) oscillation around the threshold – increase the proportionality range 22: Pb, increase integration time 23: ti,

decrease differentiation time 24: td, (possibly reduce the output 1 pulsing time by half, parameter 25: tc);

b) slow response - reduce the proportionality range Pb, differentiation time td and integration time ti;

c) overshoot - increase the proportionality range Pb, differentiation time and integration time ti

d) instability – increase the integration time ti.

12.7. PROGRAMMABLE CHARACTERISTICS (RAMPING)

Setting of parameter 27: rAMP (see section 10, Table 10) to MAnv or Auto allows to program the device as a 4-

step process controller, implemented by output 1, according to the diagram in presented fig. 12.7. This mode of

operation can be started manually at any time

(when parameter 27: rAMp = MAnv or Avto) and

automatically (rAMp = Avto) when the control

process begins (after powering up, and also using

the [F] button or BIN binary input when parameter

34: Func = StSP, section 9.1). To manually turn the

process controller on (on) or off (oFF)use the P-St

function available in the quick access menu

(section 11).

F

Fig.12.7. 4-step process controller operation diagram

Successive process stages are signalled by the messages displayed alternately with the set value (Set1 or Set2):

- Pr-1 - stage 1 – reaching the value of threshold 9: Set1 with the set gradient (28: rAr)) - ramping

- Pr-2 - stage 2 – implementation of the 1st hold time 29: at the Set1 level (with hysteresis 10: H1),

the value of parameter th1 = 0 keeps permanently the stage Pr-2

- Pr-3 - stage 3 – reaching the value of threshold 13: Set2 at full power

- Pr-4 - stage 4 - implementation of the 2nd hold time 30: th2 at the Set2 (with hysteresis 14: H2 )

the value of parameter th2 = 0 keeps permanently the stage Pr-4

- End - end of process (output 1 permanently off)

In addition, it is possible to assign the output 2 or 3 to the process when parameter 12: out2 or 15: out3 equals:

rEon - output on after process end (off during the process)

rEoF - output off after process end (on during the process)

rEP3 - output on for stages Pr-3 and Pr-4

Operation in the process control mode precludes the PID autotuning and PID adjustment.

12.8. MANUAL AND REMOTE CONTROL OPTION

The manual mode allows to set the output signal over its whole range (0 ÷ 100% ), and consequently the enables

the open control loop operation (no automatic relationship between the measured value and the output signal).

The manual mode is available independently for each controller output and is programmable by the parameters

8: out1, 12: out2,15: out3 and 18: outA section 10, Table 10. In addition, output can be configured for a quick

(unconditional) manual mode controlled by:

- the function button [F] or binary input BIN, by suitably programming the parameter 34: Func (section 9.1),

- sensor measuring errors (exceeding the range or failure), when 7: Fto1 or 11: Fto2 is equal to hAnd

In case of switching outputs (1, 2, 3), the change of output signal involves setting the filling ratio (using the

parameter 26: HSEt) with pulsing period defined by parameter 25: tc The manual mode set value 26: HSEt = 0

means that the output is permanently off, value 100 means it is permanently on. This value can be set using the

[UP] and [DOWN] buttons (only for output 1, section 12.1) or the quick access menu (section 11), and alternatively

in the parameter configuration mode (from keypad or remotely via the RS485 serial port or PRG, sections 10, 14 ÷

16 ).

14. CONNECTING TO THE PC AND AVAILABLE SOFTWARE

Connecting the controller to the PC can be useful (or necessary) in the following situations:

− remote monitoring and recording of current measurement data and process control (outputs status);

− quick configuration of parameters, including copying the settings to other controllers of the same type.

In order to establish a long range communication, set up the connection in the RS485 standard with port available in the

computer (directly or by means of the RS485 converter), according to the description in section 15.

20

In addition, the controllers as a standard are equipped with PRG ports which allow to connect to the PC via the AR955

programming device (without galvanic isolation, cable length 1.2m). To use both the programming device and the RS485

port, the supplied serial port drivers must be installed on the computer.

The communication with the device is based on the protocol compatible with MODBUS-RTU (section 16).

The following applications are available (on CD in the kit with the AR955 programming device, or for downloading

from www.apar.pl – Download tag – for Windows 2000/XP/Vista/7/8):

NOTE: !

Before making the connection, make sure that the controller’s MODBUS address (parameter 36: Addr) and the

baudrate (37: br ) are identical to the settings of computer program. In addition, set in the program options the

number of the COM serial port (for the RS485 converter or AR955 programming device it is the number given by

the operating system during installation of the drivers).

15. RS485 COMMUNICATION INTERFACE (acc. to EIA RS-485)

Length of the RS485 cable – max. 1km Max. number of devices

in the RS485 line: 30. To increase the number of devices use

RS485/RS485 amplifiers. Termination resistors when MASTER

is at the beginning of the line (see fig. above):

- at the beginning of the line: 2 x 820Ω to frame and to +5V of the MASTER and 150Ω between lines,

- at the end of the line: 150Ω between lines.

Termination resistors when MASTER is in the middle of the line:

- at the converter: 2 x 820Ω to frame and to +5V of the converter,

- at both ends of the line: 150Ω between lines.

Devices from different manufacturers forming a network 485 (eg converters RS485/USB) may have a built-in

termination resistors, and then there is no need for external components.
